Abstract
Embodiments of the invention are directed to input devices configured for use with computing devices. The present invention relates to input devices configured with a plurality of sensors configured to determine the displacement and position of the input device. Tracking of the input device may be switched from an optical sensor to an inertial sensor based on the speed of movement of the input device or based on the input device detecting that loss of tracking has occurred. In some embodiments, a gyroscope may be configured to modify data from the inertial sensor module to correct for fictitious accelerations generated when the input device is rotated.
